The last Mexicans survive next to the border wall with the US, most of them migrants or deportees trapped in the area. The urbanization of Tijuana fails to include them; environmental and all other types of degradation in this area turn them into social detritus, providing a convincing portrait of our throwaway culture. A First World mall stands on the other side of the wall; on this side, people reuse industrial waste and the surplus production of modern societies.
Many of them were once workers and consumers in the US. Once disposed of, they continue to be consumers on this side, but of drugs. They go on using consumer goods but those they pick up off the streets. They build their dwellings out of cardboard, cloth or industrial waste and eat the waste from transnational restaurant chains.
They are the last Mexicans in every sense. They are the last bastion against the US, the last line of the Third World and the last to be considered in any social program. Nevertheless, they survive, each telling a story of social, political, economic and environmental degradation. In short, they are the detritus of production and consumption chains.
